Drag racing????? 1/4 mile times and speeds...

[chevnut55]

has anyone expermented with turbos or nos? also straping the front down low as possable will nock close to 1/2 sec. off.i can see knocking much more weight off the bike. i wish n.e. dragway was not covered in snow!

chevnut, a guy on badweb has completed a turbo setup on his 05 1203 I believe. ~160hp 130 ft/lbs.

 

[chevnut55]

found it,its clean looking too,i wonder if he sells them...

I read a great article about a road race guy,Vance breese,who used to race here in the clubs I did.The article was really about his Iron horse sportster . It was converted to 79'' via cast aluminum cylinders,made by a guy named sputhe.John ulrich and staff,went to o.c.i.r. The bike had the stock 4 speed trans it came with.the bike dynoed over 100 at rear wheel and was geared for 160 top speed.The could not get out of 11s until launching in 2nd gear.Has any one tried this yet?

 

[xtreme6669]

I can't see any good coming from a 2nd gear launch!

 

[buelladdicted]

I dont think your 1125r would benefit from a second gear launch either.You have a motor thats over square,revs at least 3000 rpms higher,has a 6 speed trans.But a 1200 air cooled under square buell just might.Not having the place to run a quarter mile unless driveing way north anymore,And since I just gave an example of how it was an advantage for the bike I wrote about,Im curious.

 

[xtreme6669]

It works great for motocross starts but in that situation its controlled tire spin.... at the drag track you want no spin. Do you have a link to the article? I would like to read more about that?

 

[buelladdicted]

I read it in an actual mag,I have it somewhere,when I find it Ill let you know .Ill figure out how to scan it or you may find it at the library archives.Its a great article anyway,even if the info isnt useable.Ill get back

"Each bike has it own little secrets and the Buell's secret is straight line times are low."

Maybe on an XB... LOL

I'm totally kidding!

I agree... you wont know until you try it but I also predict nothing good out of it!

 

[chevnut55]

im taking mine to the track next weekend. what should i set the suspension at? any other advise?

 

[anrkizm95]

depends on your weight,track temp,air pressure and how you launch.i set mine real soft in the rear no adjustment to the front and had my tire pressure around 28-30 rear came off the line at around 4300 rpm laying over the air box and quite a bit of force on the front end.carried the front wheel 1st and 2nd shifted at about 6800 rpm.and ran a 11.24 or 11.25 i remember the run before that i left at 4800 and almost looped it that run i remember clearly.

 

[chevnut55]

dont want to loop! i was thinking set the suspension hard front and rear. front tire 35 lbs and rear 25lbs.
i was also thinking of reversing the sift linkage,and leaving in 2nd gear. i did it in my 67 cobra to stop wheel spin and skip a shift and it worked.
when you shift,did you use the clutch?

 

[anrkizm95]

Yes I used the clutch.it will take 6-7 runs to get your best down unless you hit it on the few but you wont know it until you compare all of them.I have an app for my phone that gives 1/4 mile times and 60 ft and top speed so when I went I only had to deal with track conditions not bike set up so much

 

[thomas_cronan]

i have only run my 99 s3 tuber best 1/8th was 7.39@99mph with a pro race muffler and race ecm(no tune). i want to run a 1/4 with it but closest is 3hrs away.

 

[chevnut55]

i made 3 runs a new england dragway with my xb12r with a race pipe/ecm,breather and airbox mod. 25 lbs rear tire pressure. got thee early the track was cold . 1st pass was like i was on ice all the way down ran a 12.87@110. 2nd run got better spun the wheelied into 2nd ran 12.64 @ 114.27. last run the track was good clean start but torq wheelie in the mid 2nd gear but was the best run.

it was good fun,my brother broke into the 10s with his ninja zx10...id like compete somehow with my bike only if he would do a track day.. i last raced my ninja it was completlet different,on the ninja it was fast and easy very predictable,on the buell it was more fun because of the torq, it still felt like i was running 10s.
my advise if you have never raced do it,its the most fun you can have on your bike. just stay in the car tire marks and pin it.

I've only race my super tt one time against a 2008 Night Rod Special who runs mid to hig 11's. I smoked him. My bike is 102 HP at the rear wheel. We shut down at about 120 and I had him by a full 80 feet.

Not scientific but good enough for a dirt bike, if I had to guess I'd say 11.25.
